Abstract: An optical fibre ribbon structure (11) comprising a plurality of optical fibres (1) and at least one flexible elongate reinforcing element (2) of substantially resilient material, arranged side by side and embedded in an elongate body (3) of plastics material, wherein the or each resilient reinforcing element is set in such a form that the ribbon structure (11) follows a path of smoothly curved undulations (4) whose axes of curvature lie transverse to the longitudinal axis of the ribbon structure, the arrangement m being such that, when the undulating ribbon structure is subjected to a tensile force, the ribbon structure straightens in a lengthwise direction against the action of the undulating resilient reinforcing element or elements thereby reducing the tensile force applied to the optical fibres and when the tensile force is removed, the ribbon structure returns towards its original undulating form. - (10pp) EPAB- EP-130728 B An optical fibre ribbon structure (11) comprising a plurality of optical fibres (1) and at least one flexible elongate reinforcing element (2) of substantially resilient material, arranged side by side and embedded in an elongate body (3) of plastics material, wherein the or each resilient reinforcing element is set in such a form that the ribbon structure (11) follows a path of smoothly curved undulations (4) whose axes of curvature lie transverse to the longitudinal axis of the ribbon structure, the arrangement m being such that, when the undulating ribbon structure is subjected to a tensile force, the ribbon structure straightens in a lengthwise direction against the action of the undulating resilient reinforcing element or elements thereby reducing the tensile force applied to the optical fibres and when the tensile force is removed, the ribbon structure returns towards its original undulating form. (10pp) GBAB- GB2141558 B An optical fibre ribbon structure comprising a plurality of optical fibres and at least one flexible elongate reinforcing element of substantially resilient material arranged side by side and embedded in an elongate body of plastics material, wherein the or each resilient reinforcing element is set in such a form that the ribbon structure follows a path of smoothly curved undulations whose axes of curvature lie transverse to the longitudinal axis of the ribbon structure, the arrangement being such that, when the undulating ribbon structure is subjected to a tensile force, the ribbon structure straightens in a lengthwise direction against the action of the undulating resilient reinforcing element or elements thereby reducing the tensile force applied to the optical fibres and when the tensile force is removed, the ribbon structure returns towards its original undulating form. USAB- US4630887 A The structure comprises optical fibres and flexible reinforcing elements of resilient material arranged side by side and embedded in an elongate plastics body. Each reinforcing element is set in such a form that the ribbon structure follows a path of smoothly curved undulations whose axes of curvature lie parallel to one another and normal to the longitudinal axis of the ribbon structure. - When the undulating ribbon structure is subjected to a tensile force, the ribbon structure straightens in a lengthwise direction against the action of the resilient reinforcing elements thus reducing the tensile force otherwise applied to the optical fibres. When the tensile force is removed, the ribbon structure returns towards its original undulating form. - (8pp)
